git clone git://git.yoctoproject.org/poky
git checkout dunfell

source poky/oe-init-build-env

• After source, YOU NEED TO CHANGE local.conf FILE IF YOU DON'T WANT TO BUILD FOREVER

/* build/conf/local.conf*/
...
BB_NUMBER_THREAD = "4" // Change number with your CPU spec
PARALLEL_MAKE = "-j4" // too

/* build/ */
bitbake core-image-minimal -k
